Zebra Accordion  Tweet

A tiny (3 KB minified, 1.3KB gzipped), easily configurable, fully customizable, cross-browser jQuery accordion plugin

npm Total Monthly License

Zebra Accordion is a tiny (3KB minified, ~1.3KB gzipped) jQuery accordion plugin. It transforms a basic definition list, without requiring any specific markup, into a small-footprint, easily configurable, fully customizable, cross-browser accordion widget, useful for better organizing larger groups of content.

Features

  • no additional markup required other than a basic definition list
  • no default style allowing you to fully customize it to suit your needs
  • works with responsive layouts
  • allows for a single expanded tab at a time, or for any number of tabs to be expanded/collapsed
  • allows for tabs to expand on mouse over, not just on click
  • if an expanded tab's content is not in the viewport it automatically scrolls the browser window so that the content is visible
  • callback functions can be used for further customizations
  • works in pretty much any browser - Firefox, Chrome, Safari, Edge, Opera and Internet Explorer 6+

Requirements

Zebra Accordion has no dependencies other than jQuery 1.7.0+

Installation

Zebra Accordion is available as a npm package. To install it use:

# the "--save" argument adds the plugin as a dependency in packages.json
npm install zebra_accordion --save

Zebra Accordion is also available as a Bower package. To install it use:

# the "--save" argument adds the plugin as a dependency in bower.json
bower install zebra_accordion --save

How to use

First, load jQuery from a CDN and provide a fallback to a local source like:

<script src="https://code.jquery.com/jquery-3.3.1.min.js"></script>
<script>window.jQuery || document.write('<script src="path/to/jquery-3.3.1.js"><\/script>')</script>

Load the Zebra Accordion jQuery plugin:

<script src="path/to/zebra_accordion.min.js"></script>

Alternatively, you can load Zebra Accordion from JSDelivr CDN like this:

<!-- for the most recent version, not recommended in production -->
<script
  src="https://cdn.jsdelivr.net/npm/zebra_accordion@latest/dist/zebra_accordion.min.js"></script>

<!-- for a specific version -->
<script
  src="https://cdn.jsdelivr.net/npm/zebra_accordion@1.2.8/dist/zebra_accordion.min.js"></script>

<!-- replacing "min" with "src" will serve you the non-compressed version -->

Load the style sheet file from a local source

<link rel="stylesheet" href="path/to/zebra_accordion.min.css">

...or from JSDelivr CDN

<!-- for the most recent version -->
<link
  rel="stylesheet"
  href="https://cdn.jsdelivr.net/npm/zebra_accordion@latest/dist/zebra_accordion.min.css">

<!-- for a specific version -->
<link
  rel="stylesheet"
  href="https://cdn.jsdelivr.net/npm/zebra_accordion@1.2.8/dist/zebra_accordion.min.css">

<!-- replacing "min" with "src" will serve you the non-compressed version -->

You need a basic definition list for your HTML markup

Don't forget to add the Zebra Accordion class to the list container! If you'll have a look you will see that all it does is to set display:hidden the all the tabs and add cursor:pointer to titles, so it will not add overweight to your CSS and that you will have to style the accordion to suit your needs.

<dl class="Zebra_Accordion">
    <dt>Lorem ipsum dolor sit amet consectetuer</dt>
    <dd>
        Lorem ipsum dolor sit amet consectetuer facilisis lacinia sapien ac et.
        Quis hendrerit neque congue pretium iaculis justo laoreet orci elit condimentum.
        Eros natoque Curabitur accumsan eget quis porttitor Sed Vestibulum amet sed.
    </dd>
    <dt>Lorem ipsum dolor sit amet consectetuer</dt>
    <dd>
        Lorem ipsum dolor sit amet consectetuer facilisis lacinia sapien ac et.
        Quis hendrerit neque congue pretium iaculis justo laoreet orci elit condimentum.
        Eros natoque Curabitur accumsan eget quis porttitor Sed Vestibulum amet sed.
    </dd>
    <dt>Lorem ipsum dolor sit amet consectetuer</dt>
    <dd>
        Lorem ipsum dolor sit amet consectetuer facilisis lacinia sapien ac et.
        Quis hendrerit neque congue pretium iaculis justo laoreet orci elit condimentum.
        Eros natoque Curabitur accumsan eget quis porttitor Sed Vestibulum amet sed.
    </dd>
    <dt>Lorem ipsum dolor sit amet consectetuer</dt>
    <dd>
        Lorem ipsum dolor sit amet consectetuer facilisis lacinia sapien ac et.
        Quis hendrerit neque congue pretium iaculis justo laoreet orci elit condimentum.
        Eros natoque Curabitur accumsan eget quis porttitor Sed Vestibulum amet sed.
    </dd>
</dl>

Now, within the DOM-ready event do

$(document).ready(function() {

    new $.Zebra_Accordion($('.Zebra_Accordion'));

});

Configuration options

Properties

Property Type Default Description
animate_opacity boolean TRUE Should a tab's opacity be also animated when expanding/collapsing?
collapsible mixed FALSE - when set to TRUE it indicates that all tabs can be collapsed
- if set to FALSE, an expanded tab can be collapsed only by expanding another tab
- if set to 0, the behavior is the same when set to FALSE with the difference that an open tab can also be closed.
expanded_class string Zebra_Accordion_Expanded The name of the class to append to an expanded tab's associated title element.
Use it to customize the aspect of expanded tabs.
hide_speed integer 400 The speed (in milliseconds) to use when collapsing a tab.
scroll_speed integer 600 If an tab's content is not entirely visible once it is expanded, the browser window will be scrolled so that the entire content is visible (if it is possible).
This value represents the speed (in milliseconds) used for scrolling browser window to the right position.
show_speed integer 400 The speed (in milliseconds) to use when expanding a tab.
show mixed 0 The index (0 based) of the tab to be expanded by default.
The value of this property can also be boolean FALSE, indicating that all tabs should be collapsed by default.
If the value of the collapsible property is TRUE, the value of this property can also be boolean TRUE, indicating that all tabs should be expanded by default. In this case, you can also provide an array of indexes to be expanded by default.
toggle_on_mouseover boolean FALSE Set this to TRUE if tabs should be expanded when hovering the mouse over their associated titles.

If the collapsible property is TRUE, this property will always be considered as FALSE!
